Im thinking of buying a Beneteau 50.5 cyclades,based in the Caribbean, can any one give any advise on these yachts as to whether they are good long distance cruisers, it will be my first yacht. I know they were built for the charter market but any advise would be much appreciated my budget is $100,000ish

Welcome! I'd be more concerned about the survey of the particular boat and how it fits your particular preferences than the model per se. Do you like it? Will your budget cover anything that needs changing before you cruise?
